NON-REFILLABLE BOTTLE SPECIFICATION forming part of Letters Patent No.r767,530, dated August 16, 1904.

l Application filed October 15, 1903. Serial No. 177,109. (No model.)

To all whom it 717/04/ concern:

Be it known that I, ARTHUR W. SWANBERG, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inNon-Refillable Bottles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to non-reiillable bottles, and has for its objectto simplify and irnprove the construction thereof. Y

To the above ends the invention consists of the novel devices andcombinations of devices hereinafter described, and defined in theclaims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a vertical section taken centrally through a bottle designedin accordance with my invention. Fig. 2 is a horizontal section on theline x2 002 of Fig. 1, and Fig. 3 is a hori- Zontal section through theso-called lockstopper on the line m3 w3 of Fig. l.

The numeral l indicates the body of the bottle, and the numeral 2 theneck thereof. The neck 2 is formed with internal screw-threads 3,extended throughout about the intermediate one-third of its entirelength, so as to leave a smooth seat above the said thread, into whichan ordinary cork (not shown) is adapted to be inserted in the usual way.

At the junction of the neck 2 with the body 1 is a valve-seat 4. Fromthe valve-seat 4 parallel guide-ribs 5 extend upward, but terminate aconsiderableA distance below the threads 3. The bottle is of courseusually made of glass, and the ribs 5, as well as the threads 3, will beintegrally formed as part of the neck of the bottle.

A glass ball-valve 6 closely fits within the cage formed by theY ribs 5and is adapted to close the opening through the valve-seat 4 eX- ceptwhen the bottle is inverted.

To hold the valve 6 in working position, I provide a so-calledlock-stopper of novel ing a radial slit at 9. The severed portions ofthe disk 7 adjacent to the slit 9 are bent one upward and the `otherdownward, so as to give the disk a sort of a spiral form and adapt thesame to be passed with a screw-like action through the threads 3 andinto the space between the said threads and the upper extremities of theribs 5. An imperforate protectingdisk l0 is rigidly attached to the disk-7 by a connecting-stem 11. The protecting-disk l() is of such diameterthat it may be passed through the neck of the bottle without engagementwith the threads 3-that is, it is of less diameter than the diameter ofthe clearance through the threaded section. The disk 7, as alreadyindicated, is of such diameter that it -can be passed through thethreaded section only by a screw-threaded engagement therewith. The twodisks 7 and 10 and the neck 11 are preferably formed integral and ofglass, and to enable the stopper to be screwed into working position, asshown in Fig. l, it is also preferably formed with a long stem 12.(Shown only by dotted lines in Fig. 1.) The stem 12 at its junction withthe disk 10 is so formed that it may be readily broken therefrom. Bymeans of the stem the lock-stopper is given a spiral movement, which isnecessary to force `the same through the threaded section into workingposition, and this having been done said stem 12 is broken 0H?. When thelockstopper has been thus placed in workingposition and the stem 12broken ofi", it will be practically impossible to work the saidlockstopper out of working position.

The lock-stopper holds the ball-valve 6 in position, so that when thebottle is not inverted or turned upside down the said valve will closethe valve-seat 4 and prevent the introduction of liquid into the bottle.When, however, the bottle is inverted, the ball-valve will run againstthe lock-stopper and the liquid will nd ready escape first through thevalveseat 4, thence through the grooves between the ribs 5, thencethrough the perforations 8 of the disk 7, and thence outward around thedisk l0. The so-called protecting-disk 10 prevents the insertion of atool into the perforations of the disk 7 and, as the said disk 10 isperfectly smooth, it will be impossible to get sufiicient grip upon thelock-stopper to screw the same from working position.

The device described is of small cost, may be made entirely of glass ornon-corrosive materials, and is thought to be eflicient for the purposeshad in view.

It will of course be understood that the construction described iscapable of modification within the scope of my invention as herein setforth and claimed.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

l. The combination with a bottle having a valve-seat 4 and formed Withinits neck with a plurality of ribs 5, and internal threads 3 said threadsterminating outward of said ribs 5, of a ball-valve 6,coperating withsaid valveseat 4, and a lock-stopper made up of a perforated spiral disk7 and connected imperforate disk l which lock-stopper is adapted to bescrewed through said threads into working position, substantially asdescribed.

2. The combination with a bottle having a valve-seat 4 and formed withinits neck portion with a plurality of ribs 5 and internal threads 3, saidthreads terminating short `of said ribs 5 and of the outer end of saidneck,- of a ball-valve 6 cooperating with said seat 4, and alock-stopper made up of a perforate spiral disk 7 and imperforate diskl0, said disks being connected by the neck ll, and having an extendedstem portion l2 adapted to be broken off after said stopper has beenscrewed into workingv position, substantially as described. j

In testimony whereof I aiiX my signature in presence of tWo witnesses. i
